False PO4 reading

[Lasse]

If I understand it right - its a 40 gall0n tank that has been running for 4 weeks?

Sorry no. It's. 30 gallon IM fusion all in one been running almost 3 years. I lost a Midas blennie a few weeks ago which I think started the issue.

If you do not dose organic carbon - it’s a possibility (IMO) that you really has 0 ppm PO4 and a very low production of it.

I think that if you lower the biomass of algae with mechanically take away (as you intend to do) or/and add some grazers things will be better

i don't dose carbon. Do you think it would help if I did?

 

[Lasse]

No - not when you read 0 or low levels of PO4 and NO3

I'll just continue manual removal. Any thoughts on dosing h2O2 to rid the hair algae?

I´ll really do not know if H2O2 will make it better in this case. I normally walk the hard way – mechanical remove of the older algae and after that adding grazers. Sometimes – when I have had algae on rocks that I couldn’t take out - I apply H2O2 direct on the algae with help of a syringe. But – be careful if you test this.

Since I'll be transferring everything to a new system in a few weeks I'll just keep at it the old fashion way.
